Jetman Attempts Intercontinental Flight 140

Posted by samzenpus on Wednesday November 25, 2009 @01:32PM from the a-jetwing-and-a-prayer dept.

Last year we ran the story of Yves Rossy and his DIY jetwings. Yves spent $190,000 and countless hours building a set of jet-powered wings which he used to cross the English Channel. Rossy's next goal is to cross the Strait of Gibraltar, from Tangier in Morocco and Tarifa on the southwestern tip of Spain. From the article: "Using a four-cylinder jet pack and carbon fibre wings spanning over 8ft, he will jump out of a plane at 6,500 ft and cruise at 130 mph until he reaches the Spanish coast, when he will parachute to earth." Update 18:57 GMT: mytrip writes: "Yves Rossy took off from Tangiers but five minutes into an expected 15-minute flight he was obliged to ditch into the wind-swept waters."

It sounds like they are guessing passwords rather than cracking keys. But is there any advantage in using a CELL processor for this?

AES, for example, is the encryption standard used by PGP's whole disk encryption. From
http://en.wikipedia.org/wiki/Brute_force_attack:

"AES permits the use of 256-bit keys. Breaking a symmetric 256-bit key by brute force requires 2128 times more computational power than a 128-bit key. A device that could check a billion billion (1018) AES keys per second would require about 3×1051 years to exhaust the 256-bit key space."

Hence my thought that they are not cracking keys.
